This communicates via SPI to the host microcontroller. This contains a ΔΣ ADC, and a pair of Programmable Gain Amplifiers on the input, together with some multiplexing. The final bit of conversion of the input waveform is performed by a Texas Instruments ADS1291, a 2-channel 24-bit Analogue front-end specifically designed for Bioelectrical measurement such as ECG. To the right of that is a SiLabs Si8622ED single channel digital isolator IC. There’s a 100MΩ resistor across the isolation barrier, probably for ESD bonding. The isolation transformer is visible on the left here, next to the 8-pin header that connects to the main PCB. Signal IsolationĪ 5kV isolation barrier is provided between the rest of the unit & the acquisition board, both for the data path & power path. This array of protection components serves two purposes – protection of the instrument against defibrillator voltages & protection of the patient from electrical shock by the instrument. The bottom of the PCB has the DB-25 connector, along with the input protection diodes & resistors. The bottom edge of the PCB has a trio of HJ4051 high speed analog multiplexers, which are switching the ECG leads onto the Ultra-Low Power Op-Amps on the right, a trio of TCL2254A devices from Texas Instruments, before being sent on to the ADC. The DB-15 connector is on the right hand side, where the ECG leadset connects. The first of 3 PCBs inside the shell is the acquisition PCB, with all the patient-connected circuitry. The FFC to the LCD & button pad is currently keeping things connected together. Internalsģ Philips screws hold the unit together, and once those are removed, the shell halves separate.

There aren’t any markings on this at all, but I do know from the manual it’s a 7.4v 2S Li-Ion pack, energy capacity is another unknown, but there is very little weight to the battery, so it can’t be that large. Underneath can be seen the top of the battery pack, which just clips into place.

From the serial numbering, it looks like my unit was manufactured on 3/11/19, and was the 8th unit off the production line. The rear has the laser-marked rating plate, with all the specifications & regulatory markings. There’s a thermal printer for rhythm strips, printing onto 50mm wide paper rolls. Readout is provided on a dot-matrix LCD, which is brightly backlit. Control ButtonsĬontrol is via the front panel, with some large buttons.

This is a single channel, 12 lead unit – meaning it’s a full 12 lead ECG, but it records one lead at a time, in sequence. This is the ECG80A handheld Electrocardiograph.
I figured it was about time I added to the medical kit, and since Contec, who makes my SPO² meter seems to have a decent level of manufacturing quality, one of their ECG machines seemed like a good choice.

It can perform a series of tests for the oximeter by simulation means, and gives cognizance of veracity about the oximeter.īecause the oximeter manufacturer may use different R-curves, some R-curves used abroad currently have been embedded. MS100 SpO2 Simulator is a kind of Separated SpO2 simulator, small and light.
